Problems solved by technology

[0003] All there is following defective in above two ways: 1, the end of the straight thread thread head of the steel bar that processes often has burr, and this burr can bring following problem: the one, may be screwed in the connection sleeve when screwing into the straight thread connection sleeve. The threaded buckle is bumped, which is not easy to screw in and even causes damage to the threaded buckle, resulting in waste products; the second is the burr at the end of the straight thread thread head, which will cause a gap between the butt end faces of the two steel bars after the butt joint, and the contact surface is small, so that when the pressur

Abstract

The steel bar end chamfering and rounding roller includes at least three eccentric chamfering and rounding shafts, each of which consists of an eccentric chamfering section, a main shaft section and an eccentric rounding section. The eccentric chamfering section and the eccentric rounding section has eccentric phase difference of 90-180 deg; the eccentric rounding section is provided with rounding wheel; the eccentric chamfering section is provided with corresponding chamfering cutter; and the main shaft section is provided with outer gears meshed to the same inner gear sleeve. There are also dialing disc, locating part, locating ring with locating notch and spring, and the locating part and the locating notch are fitted in different phases corresponding to three states, including chamfering, rounding and free position. The present invention is used in chamfering and rounding steel bar before rolling for raised final steel bar quality.

Description

technical field [0001] The invention relates to processing equipment for connecting wire heads of steel bars in the construction industry, in particular to a steel bar chamfering rolling and rounding device. The front-stage process of the steel wire head, in order to finally improve the quality of the steel wire head. Background technique [0002] At present, the mechanical connection of steel bars in the construction industry is the main trend, and the direct rolling straight thread mechanical connection and the stripping rib rolling straight thread mechanical connection are the dominant trends. Among them, the direct rolling straight thread mechanical connection is to directly roll out the straight thread thread head with the rolling thread head device at the end of the steel bar, and then connect the steel bars with the straight thread connecting sleeve. The stripping rib rolling straight thread mechanical connection is to first cut off the ribs on the end surface of the...
